Reliable Protection for Your Fermentation

The S-Shaped Double-Bubble Airlock is a simple yet effective tool for ensuring a smooth fermentation process. Its one-piece design provides a clear pathway for CO2 to escape while preventing air, bacteria, and wild yeast from entering your fermenter. This airlock is an excellent choice for homebrewers and fermenters seeking durability and ease of use.

Why Choose an S-Shaped Airlock?

The double-bubble design offers key advantages:

  • No Moving Parts: Unlike 3-piece airlocks, there are no small components to misplace, making it ideal for those who prioritize simplicity.
  • Clear Construction: Transparent plastic allows you to monitor activity with ease.
  • Durable and Reusable: Made from sturdy, food-grade plastic, this airlock is built to last batch after batch.

Enhanced Protection with Star San

We recommend filling the airlock with Star San solution instead of water for an extra layer of protection. This is especially important during:

  • Temperature Drops: A rapid temperature drop can create a vacuum inside the fermenter, potentially drawing contaminants. Star San prevents this.
  • Slowed Fermentation: When CO2 production decreases, Star San enhances the airlock’s ability to safeguard your brew.

Versatile Applications

The S-Shaped Airlock is suitable for use in a wide range of fermentation projects:

  • Beer
  • Wine
  • Mead
  • Cider
  • Kombucha

How to Use the S-Shaped Airlock

  1. Fill the Airlock: Add Star San or water to the fill line.
  2. Attach to Fermenter: Insert the airlock into a stopper or fermenter lid with a snug seal.
  3. Monitor Activity: Watch the bubbles to track fermentation progress.
